- Application
All surfaces should be smooth, clean, dry, sound and free from frost, oil, grease, condensation and other contamination. Product may be applied to ‘green’ concrete. The minimum ambient temperature for application is 5°C, it is not recommended to apply the product at temperatures below this as specified drying times will not be achieved. Product is recommended to be brush or roller applied, avoid pouring directly onto a horizontal surface. This may cause puddling during application and increase drying time. Should the product require thinning, it is recommended to thin 5-10% by volume of white spirit initially and evaluate the resulting viscosity. The product should not need to be thinned if recommended storage conditions have been maintained.
The product can be applied as a single coat in certain applications but two coats is universally recommended. Performance is improved where the second coat is applied at right angles to the first but it is not essential to do so. Leave 2-4 hours before overcoating with the second coat. A touch test on the 1st coat will indicate readiness. If applying to metal, ensure the surface is well prepared in advance. Wire brush off any rust and ensure clean and dry. Where long-term protection is required treat with a rust-inhibitive product such as red lead or zinc phosphate.
- Recommended Number of Coats
Two recommended, however in severe conditions three coats for maximum protection. Allow 24 hours drying time between coats.
- Thinners
Not normally required, however the paint may be diluted with BSS245 Barrettine White Spirit in order to adjust the viscosity for spraying.
- Cleaning
Tool etc may be cleaned with Barrettine White Spirit.

Storage & Handling
- Storage
Product is not chemically sensitive to heat or cold but extreme temperatures should be avoided. Product should be stored in well-maintained storage tanks if bulk received or in the original manufacturer packaging if packaged. Do not store with oxidisers and keep away from sources of ignition, the product is flammable. The product has an infinite shelf life provided its container has not been opened. If opened, the product should be used within 24 months. Longer storage times may result in the bitumen dropping out of solution to the base of the container, rigorous and thorough stirring is therefore advised prior to application.
